is asimilar 4View with the lower portion ofl the shield broken away to disclose the interior construction, and, Fig. 3 is a` top view' of the. agitator section.

Like letters referto like par-ts throughout the several views. Y In the embodimentof my invention shown l in the drawings, I have shown abi-part structurefconsisting of two cylindrical por'- tions Aa and b one of which asa, carries an u '4 carnes a filter 'or screen d. These parts are agitator c and the other part -b of which separately connected by means of a bayonet 4slot and pin connection, as shown in Fig. 1V

of the drawings.' The part b also has a plursdityjof projections e' adapted to enter bev` f ,tween the adjoining ends of pipe 'sections in the 'intake conduit (indicated in dotted lines Y in 1) for the purpose o f preventing the creeping or displacement of the attachment in'its entirety. Theprojections e therefore serve asa means for securing the `attachment in the conduit, although, 1f desired, the

'cylindrical casing any orb might -have a driving :fit'w'ithin .the conduitl f The .screen orilter d Vcomprises afine mesh,.1n'etal l,ic screen projected inthe direcv Y' tion. of flow ofthe mixture, said screen being .off gradually reduced diameter, -being .'haped somewhat like a truncated con'e, the

entire area'of the Vopenings ofsaid screen permitting the egress of the mixture at all points in the direction of flow thereof, thus 'av iding anyl substantial retardation of the l same,prallel bars f g'of small dimensions i veach iof'whih hars, has Va screw-threaded 'opening Ucarrying'an exteriorlyscrew- -40- head to facilitate the 'adjustment thereof,

threaded Aa V instable ball cup having a slotted ounted in the bearings afforded by theY Acups It z' is a rotatable shaft 'y' having rigidly andA permanently. attached thereto a helicoidal strand k, the' gmatest diameter of which is such as to bring it into close proxi fixed .channel through the agitator, the op-A imity to the easing a,' and the pitch of which is such as to avoid the presence of a of a direct channel through the gagitator,'

but at the same time" increasing longitudinally the ei'ective range of-operation threof without presenting any substantial-obstruction to the iow of-the gases. This construction Valso insures the rotation of the 'Ille'.:asing 'a has.- at the opposite endsthereof and; extending diametrically .across agltator by the, flowing gases through the engagement ofsaid gases with the forward helicoidal portion thereof, thus permitting the remainder of the agitator to act directly upon then'olu'mn 'of gas.

v Itwill be observed that by thehc'onstruction above referred to, atno point within the casing a, .is there any substantialoh-'gl i struction to the flow of gases nor any such obstruction as would tend to deflect the gas toward thecasing. a, the impact of a column of gaspassing through the casing a with the agitator k occurring at diiferent points rela-tive tothe casinga. The rounded surface ofthe strand'k olers barely enoughfre-- sistance to the flowing gas to secure the 'de- 'sired vrotary. movement thereof, andthe effeet of said strand upon -the-gas is merely tator resultingl from the action' of ,the gas due to the suction from the engine causing the interruption or agitation of the entire 'column of gas in a manner -to thoroughly mix the vapor and the air, rather .than to separate the heavier vapor from the lighter' air through centrifugal action.

vto divide same, the rotation of'said agi- I I have ,found bv actual use thativ'ith a I mixer of Athe character described, I 4secure higher engine efiiciency with a given quantity of fuel. This I attribute to the more thorough ommingling of the -vapor and theA air, which results in a drier mixture, or.

rather a mixture carrying less Avapor .in sus ension as such a mixture would be'more .hig ly explosive 'than would be thecase otherwise. This condition results in greater economy in running an engine. I have also found vthat vwhen using themixe'r attach ;ment, experience no diiiiculty at the engine intake.'v This I attribute to the thorough'admixture of-,the' -vapor and the. air., without limiting orvarying in any way the quantity of fuel introduced` by each suction stroke of the engine'b'y an obstruction in the;

intake pipe or in the manifold-pipes.. I havealso found that the danger of back iirng through the intake valve is practically eliminatedA when this device is used. These conditions result. from. the 'mode of ,operation peculiar to the structure herein def The sections@ b having been by the pin and bayonet slot `connection, th mixer in its entirety is inserted in the vapor feed pipe or the manifold leading therefrom to thedi ferent cylinders" with the filter or screen d projecting toward the engine or in a direc- -tion coinciding with the How of the gases therethrough, the open mouth of thecasing a being exposed toward the carbureter proper. The parts 'being so arranged, with each suction stroke o'f the engine .piston the carburcted vapor is ydrawn through the casing a b. Passing through the first of these casings, the mixture' will rotate the helivertical, or 4relative to the radii of said cas- Y vapor and air; YThe:centrifugal-aet-ifon ofi ing and presenting no fiat surfaces' towardthe carbureter, thus not retarding thejiow' of the mixture materially orA diverting it from al substantially. direct .course through. the' casingn, while intercepting it gat"sub'' stantially every 'pointof its course nto an exl tent to causey a thoroughadmixture of the the agitator c is' insufficient to eliminate any material .quantity of the heavier fmatterin the mixture and the helicoidal arrangement of the strandk affords arontinuedtbeating action upon the column: of 'gas-suicient to secure the thorough agitation thereof with the resultant formation of a substantially dry mixture prior to its introduction to the engine. As the entire volume of air enters the screen or filter d the contour of said parts permits the escape of gas in a volume practically coinciding with the area of the easing b, thus placing no limitation upon the volume of the mixture passing to the engine 'as c omparedfvvi'th that leaving' the carbureter, Furthermore, the c nstr1ic` tion and arrangement of thisscreen or filter permits the application ofa strong suction throughl the carbureter 4itself 4which ,will of itself tend to 'increase the eiiiciency of the entire feed system including the mixer.

The arrangement of the agitator c and the screen d in sequence as shown and. de? scribed, 1sl desirable, as under most conditions of use the filter or Lscreen is an essential adjunct and to'place it between theagitator and the carbureter would not on'lytend to eliminate the vapor held in suspension in the air, but would lead to the rapid clogging of the screen or filter itself. If it be desired to use the agitator alone, lthe bi-part construction of. the mixer permitsthe removing of the screen, and this construction also facilitates the cleaning of the said screen. It is to be observed that the arrangcuientv of` the agitator and of the screen o r filter is such as to interpose no sub1 stantial obstruction 1n the course of the charge beingdrawn to the-engine, thus pre- 4 serving noriual condition throughout the vapor feed system, while insuring'a more thorough mixturethan is secured when'mcrely a va por jet. and eutraincd air ar.eused.`y

1t is wel] .known that the efficiency of any gas distribution system is impaired by the presence ot' any obstructions which would tend to divert the direction of the How of gas and l attribute the results attained by the actual use of my attachment to the ahseuce oi' any' such conditions, coupled with the absence 'of any direct channels which might. lea 1.o the stratification of the vapor or oi the airwhile passing from the carburetor proper lo the engine cylinder,

In the -accompanying drawings Vlf have 3431.1' .l '1,007,010' i y 8 shown my invention in that' form which I l `have l,found to possess high eliiciency in actual., use, but nevertheless, I do not intend to limit myself tothe precise details of, construction embodied in the deviceshown in the drawings, it being' apparent rthat such .1 may be varied'W-ithout departingfrom" tl'1e` spiritl and scope of-the invention.

Having described the mvention, what I claimv as new andl desire to' have protected by Letters Patent, is
